考虑滑面材质的碎屑流试验堆积特征分析
Analysis of the accumulation characteristics of the debris flow experiment considering slip surface material
摘要
Abstract
In order to analyze the movement and accumulation characteristics of rock avalanche,a laboratory experiment was set up indoors,and designed with 4 factors,namely,gradation,slope angle,quality of debris flow,and slip surface material,which were used to analyse the effects of each factor on the accumulation characteristics of debris flows.The research results show that the reduced slope angle and rougher slip surface caused some of the particles to accumulate or be retained on the slope surface,and that there were differences in the characteristics of particle accumulation compared to when the particles were completely accumulated at the bottom of the slope.Slip surface material is basically negatively correlated with accumulation features such as stroke,and slope angle is basically positively correlated with accumulation features,and the two have the greatest influence on accumulation features.The quality of debris flow is basically negatively correlated with accumulation features,and has less influence on the distribution of particles accumulation features.Gradation has no significant correlation with particle accumulation characteristics.关键词
